you're spot on, they shouldn't really cost anything. XCode for iOS development, for example, doesn't cost anything (once you've bought a mac). similarly Android development tools don't cost a thing. charging a small fee like $99/year for the apple developer program or the Amazon store, or $25/year (i think it is) for Google Play is something they say simply helps defray the costs of hosting your apps and icons and in-app-purchase stuff, etc, reviewing apps, supporting you as a developer, and they all say it "helps improve the quality of apps in the store." To be fair, Windows development tools and access to the Windows Marketplace and the XBLGI are similarly free and/or priced (although honestly the tools are pretty stunted in free form). I was really trying to make the point that the cost on xBox for developing games that get real promotion or are easily visible to users are very high and Microsoft gets overwhelmingly strong veto power over your apps/games.

I asked about this specifically because, when I got the book that really started me deep into programming [1], I was hampered by my lack of a C compiler and assembler, and the ~$200 cost thereof ($400 total, in mid-1990's dollars, for the two tools -- kids these days have it easy with binary downloads of Windows ports of gcc and NASM available free on the web). If I'd had that kind of money in middle school, I would have blown it on video games. (I didn't know about GNU, I don't think the DOS port of gcc, the Allegro system, was yet born, and I didn't have any mentors.)

The source is messy and compiler-specific, and many implementations are irrelevant to modern systems. For example, I recall Chapter 14 is about implementing multiplayer over serial cable by directly writing to I/O ports in assembly language to drive the UART. I never did get that to work, but trying to translate the book from the Watcom C + MASM toolchain to the QBASIC + DEBUG toolchain -- without access to a working copy of the former and zero prior C experience! -- actually taught me a lot.

So maybe there is a reason toolchains should be expensive -- to encourage starving students with lots of time but little money to expand their minds by jury-rigging alternatives :)

It might interest you to know that according to http://en.wikipedia.org/wiki/DJGPP, there's been a DOS port of gcc since 1989.

This is veering a bit off topic, but Apple do a fair bit for their $100/year. Especially in regards to handling overseas tax withholding to ensure that you don't need to keep up with every country's local tax laws. They also stand between you and the customer with regards to processing refunds, volume and educational licensing.

Google Play, as far as I'm aware, don't do this for every country you sell in. Leading to situations where you may be liable for tax payments but won't know it unless you do the research yourself. This is discussed in more detail here: http://retrodreamer.com/blog/2012/03/why-dont-we-have-paid-v...

Actually it is 25$ once and for all.
